PURPOSE:To enable the easy accurate matched connection of adjacent engaged members, by using a matching driver to drive one of the adjacent engaged members through a speed reduction mechanism and a clutch mechanism. CONSTITUTION:Motor shafts 3a, 3b are coupled to each other through a first clutch mechanism 4. When motors 2a, 2b are rotated forward and backward, pushers 1a, 1b are moved back and forth in directions A. The torque of a motor 12 provided with a speed reduction mechanism 13 and a brake mechanism is transmitted to the motor shaft 3a through an output shaft 14 and a second clutch mechanism 15, Strikers 16a, 16b are so mounted that they operate limit switches 8a, 8b when the front ends 1aa, 1bb of the pushers 1a, 1b have reached prescribed positioning reference planes as a result of the backward movement of the pushers to the vicinity of their backward movement limits. |
